52816-99-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52816-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,1 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52816-99:
(7*5)+(6*2)+(5*8)+(4*1)+(3*6)+(2*9)+(1*9)=136
136 % 10 = 6
So 52816-99-6 is a valid CAS Registry Number.

Reactions of 2Н(4Н)-chromenes with dinucleophiles: one-step synthesis of 2-(1H-(bi)pyrazol-3-yl)- and 2-(1,4(5)-(benzo)diazepin-4-yl)phenols

[Figure not available: see fulltext.] Novel derivatives of 2-(1H-(bi)pyrazol-3-yl)phenols and 2-(1,4(5)-(benzo)diazepin-4-yl)phenols were obtained in the reaction of (4-amino-2H-chromen-2-ylidene)malondialdehyde and 4H-chromen-4-imines with 1,2-, 1,3-, and 1,4-dinucleophiles proceeding as a cascade reaction initiated by the Michael reaction.

The Vilsmeier-Haack formylation of 2,3-dihydro-4H-1,3-benzoxazin-4-ones and isomeric 1,2-dihydro-4H-3,1-benzoxazin-4-ones: An effective approach to functionalized 2H-/4H-chromenes and tetrahydroacridines

Farat, Oleg K.,Markov, Victor I.,Varenichenko, Svetlana A.,Dotsenko, Victor V.,Mazepa, Alexander V.

supporting information, p. 5554 - 5561 (2015/08/03)

We found that 1,3- and isomeric 3,1-benzoxazin-4-ones react with the Vilsmeier reagent in vastly different ways. Thus, either 2H- or 4H-chromenes were obtained in good yields when 1,3-benzoxazin-4-ones were reacted at 75-80 °C, while the formylation of 3,1-benzoxazines at ambient temperature leads to acridine-9-one or 9-chloroacridine derivatives, depending on the amount of Vilsmeier reagent and the nature of substrate.
